BACKGROUND Adenoid cystic carcinoma is a locally aggressive salivary gland neoplasm, which has a poor long-term prognosis. A chromosomal translocation involving the genes encoding the transcription factors, MYB and NFIB, has been recently discovered in these tumors. METHODS MYB translocation and protein expression were studied in 37 adenoid cystic carcinomas, 112 other salivary gland neoplasm...
The narrow genetic background restricts wheat yield and quality improvement. The wild relatives of wheat are the huge gene pools for wheat improvement and can broaden its genetic basis. Production of wheat-alien translocation lines can transfer alien genes to wheat. So it is important to develop an efficient method to induce wheat-alien chromosome translocation. Agropyroncristatum (P genome) ca...
Using an ultrasensitive assay involving the PCR, we have examined the frequency of a follicular lymphoma-associated translocation in peripheral blood from 132 individuals, most of whom were healthy blood donors. This translocation occurs between the bcl-2 proto-oncogene and the JH gene region and prolongs the life of lymphocytes. At a level of sensitivity of 1 translocation-bearing cell per 5 x...
Molecular dynamics simulations based on a novel polarizable nanotube model were performed to study the dynamics in translocation of a single-stranded deoxyribonucleic acid oligonucleotide through a polarized carbon nanotube membrane by an applied electric field. The study revealed a nonlinear dependence of translocation velocity and an inverse quadratic dependence of translocation time on the e...
Translocation of diphtheria toxin (DT) or ricin to the cytosol is the rate-limiting step responsible for (pseudo) first-order decline in protein synthesis observed in intoxicated cell populations. The requirements for energy utilization in the translocation of both toxins are examined by perturbing the intoxication during this period of protein synthesis decline. Translocation of either toxin i...
In this study, We demonstrated that Bax mitochondrial translocation plays a vital role in the initiation of the mitochondrial signaling pathway upon activation by heat stress. In addition, both p53 mitochondrial translocation and Ca(2+) signal mediated MPTP opening activate Bax mitochondrial translocation. Employing pifithrin-α (a p53 mitochondrial translocation inhibitor) and CsA (a permeabili...
The Tat (twin-arginine translocation) pathway is a Sec-independent mechanism for translocating folded preproteins across or into the inner membrane of Escherichia coli. To study Tat translocation, we sought an in vitro translocation assay using purified inner membrane vesicles and in vitro synthesized substrate protein. While membrane vesicles derived from wild-type cells translocate the Sec-de...
The t(12;21)(p13;q22) ETV6-RUNX1 gene fusion is one of the most common chromosomal translocation in childhood acute lymphoblastic leukemia (ALL). It is associated with favorable prognosis. The identification of the genomic sequence of the breakpoint flanking regions of the ETV6-RUNX1 translocation should be the best strategy to monitor minimal residual disease (MRD) in patients with ETV6-RUNX1-...
Exogenous brassinolide (BR) application is a feasible measure to alleviate abiotic stresses on crop productivity. The effects of BR at the silking-stage accumulation, translocation, and remobilization dry matter (DM) nutrients (nitrogen, phosphorus, potassium) waxy maize exposed post-silking high temperature (HT) were studied using Jingkenuo2000 (JKN2000, heat-tolerant) Yunuo7 (YN7, heat-sensit...
